COMBINED LAVATORY-BASIN PLUG AND OVERFLOW.

SPECIFICATION forming part of Letters Patent No.7527,802, dated October23, 1894.

Application tiled December 22, 1893. Serial No. 494,400. (No model.)

will enable others skilled in the art to which.

it appertains to make and use the same. p

This invention relates to an improvement in combined overflow tubes andplugs for lavatory basins and it consists in the construction andarrangement of parts hereinafter described and definitely pointed out inthe claims.

The aim and purpose of this invention is -the provision of improvedmeans for plugging and sealing the discharge opening of a basin, whichwill also constitute an overiow for the same, and further in theprovision of improved means for retaining the combined overflow and plugin its vertical adjustment and to also allow of an easy removal of thesame. These objects are attained by the construction illustrated in theaccompanying drawings wherein like letters of reference indicatecorresponding parts in the several views, and in which` Figure 1, is asectional elevation of the improvement and a portion of a basin, andFig. 2 is a detail top plan View of the discharge opening.

In the drawings A represents the basin, B the drain pipe and C thedischarge opening. In this opening is formed a spider D, havingathreaded nipple cl on which is mounted a vtubular upright or stem E,extending up to a point above the high water line of the basin. Thisupright is cylindrical and of uniform size through its entire length.

F represents the plug, consisting of a hollow cylinder or shell of adiameter greater than the diameter of the upright, so that anintervening space is formed. This cylinder is of a length less than thelength of the upright, and has its ends open. The lower edge of thecylinder F is formed with a suit able rubber .gasket f, which closelytits the edges of the discharge opening of the basin.

The cylinder F is slidingly held on the upright by having radial arms fformed on its inner face radiating from and fixed to collars, F', F2fitting around the upright, and allowed a sliding movement thereon. Thecollar F2 is extended up above the cylinder F and has rigidly secured onits upper e'nd a ball or handle G capped over the upper end of theupright. On the upper edge of the collar F2 within the ball is formed anintegral spring H having a curved end h constituting a catch, normallyengaging the outer face of the upright, to hold the plug or cylinder Finposition by frictional contact.

An outer cylinder or trap bell, I, is secured to the sleeve F2 abovethetop of the inner cylinder, and extends down to a point slightly abovethe lower edge of the inner cylinder. The diameter of this bell isgreater than the'diameter of the plug or inner cylinder, so that thewater may pass up between.

In operationwhen the vbasin is filled with water, to a point above theplug-cylinder the water will flow out through the cylinders. When, it isdesired to empty the bowl or basin, the ball is grasped and raised untilthe spring catch engages over the edge of the upright, which holds thecylinders in a raised position opening the discharge opening. Thepressure of the spring on the upvright will also hold the cylinder up atanyl point before reaching theend of the upright. By this means it isonly necessary to raise the cylinders, and the .trouble heretoforeexperienced in raising a cylinder and then turning the same to a properpoint to lock y it in position is Wholly avoided.

It will be observed that by simply lifting the cylinders up the same maybe quickly and easily removed from the upright, for cleaning purposesand by employing the bell, a trap is formed when a small amount of wateris placed in the basin.

It is evident that many minor changes in the construction andarrangement of the parts of the' device can be made and substi--v tutedfor those herein shown and described without in the least departing fromthe nature and principle of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 5 Patent, is-

1. In alavatory basin, the combination with an upright secured. at thedischarge thereof,`

an open end plugging cylinder, around the upright, arms, on thecylinder, collars on the inner ends of the arms fitted around theupright, an extension on the upper collar, a bell on the extension and aspring on the extension engaging the upright, substantially asdescribed.

2. In a lavatory basin, the combination with an upright secured at thedischarge thereof formed of uniform dimensions throughout; its length,of a plugging-cylinder surrounding the upright, supporting arms on theinner face of the cylinder, collars on the inner ends of the arms,surrounding the upright and a curved spring on the upper collar engagingthe upright, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.

CHARLES H. MUCKENHIRN.
